You may already know of this place, but in case you dont Ill link it here http://www.slickdeals.net
I check this page at least once a day, there is a big variety of good deals every day, and people post coupon codes and such too. One beware though, is people are kinda crude on the actual boards where they post. I just check out the front page where the best deals are posted.
Another good one is http://www.afullcup.com/forums/#front-door
and they have a Hot Deals page too. The people who post here are really friendly!
Hope these help someone out
